宁优64系我所利用宁A不育系与测64配组而成的中熟杂交早稻新组合。该组合1986年参加漳平县区试,平均亩产423公斤,比对照种威优64亩增49.4公斤,增产13.2％。1987年继续参加漳平县区试,平均亩产409公斤,仍比威优64增产,名列前茅。1987年,本所大田示范试种2亩,平均亩产504公斤,比对照种威优64亩增54公斤,增产12％。同年参加宁德地区区试,平均亩产436.5公斤,比威优64略减产,产量居第二位。但比熟期相近的78130亩增55.4公斤,增产
Ningyou 64 is a new combination of early maturing medium-maturity hybrid rice that we use Ning A sterile line with 64 test sets. The combination of Zhangping County in 1986 to participate in the test, the average yield of 423 kilograms, 64 acres more than the control Weiyou 49.4 kg, an increase of 13.2%. In 1987 continue to participate in Zhangping County trial, the average yield of 409 kg, still more than Wei You 64 yield, among the best. In 1987, the field trial demonstration of 2 acres of Daejeon, the average mu produce 504 kilograms, than the control Weiyou 64 acres by 54 kilograms, an increase of 12%. The same year to participate Ningde area test, the average yield of 436.5 kilograms, slightly less than the Wei You 64 yield, output ranks second. But 78130 mu more than the mature period by 55.4 kg, increase production
